[clang-tidy][run-clang-tidy.py] Add --config-file=<string> option

Link to the GitHub Issue: https://github.com/llvm/llvm-project/issues/53745

Added config_path variable within the python script which makes the
required call to the clang-tidy binary with --config-file option.
If the config_path is None then config will be used. No error is raised
if both are given but silently chooses config_path over config
